Formulas
Sets the left margin of the printing area. The left margin is set to ((
nH
X 256) +
nL
) times horizontal motion unit) inches.
The horizontal motion units are set by the set horizontal and vertical minimum motion units command (1D 50),
described in this manual.
The width of the printing area is set by the set printing area width command (1D 57), which follows this command.
If the setting exceeds the printable area, the maximum value of the printable area is used. The maximum printable
receipt area is 576 dots on the receipt and 420 addressable dots on the slip. See the illustration on the next page.
To set the
Receipt
left margin to one inch at the default horizontal motion unit of 1/203 inches, send the four-byte
string:
GS L 203 0
Or, to set the left margin to two inches at the default horizontal motion unit of 1/203 units per inch, send the four-byte
string:
GS L 150 1
Where 2 inches =
406
/203, and 406 = (1 X 256) + 150, derived from decimal to hexadecimal conversion:

/256 = 1 (nH) with remainder 150 (nL)
